5.0 DESIGN CRITERIA AND CONCEPTUAL DESIGN DESCRIPTION
FPL transformer clearance requirements
to the transformers and conduit via private drives, these overhead
lines may be undergrounded within existing easements and
transformers may remain at the rear of the buildings.


The Village is served by two overhead and five underground
separate main feeders from the substation that serve specific areas
of the Village based on electrical load and capacity of the main
feeder. Main feeders will not be replaced or upgraded so service
areas within the Village will remain the same.
All electrical equipment and materials to be owned and maintained
by FPL at the conclusion of the project and shall be provided
by FPL.
 Contractors installing FPL infrastructure must be pre-approved
by FPL.
 Switch cabinets will be required at each of the two main overhead
feeder landing points in the Village. Switch cabinets will also be
required to separate underground distribution transformer loops.
Forty-one overhead switches exist today. FPL has stated that
number will be reduced. To the extent practical, standard switch
cabinets are to be used. Vista style switch cabinets can be used
as circumstances may require or as requested by the Village as
previously noted.

 At least one capacitor bank will be required within the service area
of each feeder. This yields a total of seven The capacitor bank must
be located within 100 feet of a switch cabinet.
 FPL prefers 10'x10' easements for single phase transformers.
Open Delta Bank Transformers require a 13'x10' easement. Three-
phase transformers require anywhere from 10'x10' to 20'x20'
depending on the load. FPL prefers 24'x24' easements for switch
cabinets and capacitor banks. Underground feeder splice boxes
require a 7'x22' easement. Underground handhole easements
can vary between 5'x5' and 5'x20' depending on the size of the
handhole and configuration of the undergrounding wiring. Actual
easement dimensions and configurations may vary depending on
the specific situation, field conditions, and types of equipment to
be installed. Easements must be located adjacent to and accessed
from the public right-of-way.
